5 2.FEATURES & TECHNICAL EXPLANATION 2-1. FEATURES Direct Drive System The advanced Brushless DC motor directly drives the drum without belt and pulley. Water Circulation The detergent water from the drum is sprayed directly over the load ; this enables the clothes to get soaked more quickly during the cycle. The detergent suds can be removed more easily by the water shower during rinse cycle. The water circulation system uses both water and detergent more efficiently. Built-in Heater Internal heater automatically heats the water to the best temperature on selected cycles. Child Lock The Child lock prevents children from pressing any buttons to change the settings during operation. More economical by Intelligent Wash System Intelligent Wash System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption. Low noise speed control system By sensing the amount of load and balance, it evenly distributes load to minimize the spinning noise level. Safety device (Aqua lock) Aqua lock System is designed for detecting water leakage during operation to prevent water from spilling on the floor. Steam Washing and Refresh Steam Washing features upgrade washing performance with low energy consumption. Refresh cycle reduces wrinkles from dry clothes.

6 2-2. DETERMINE WASHING TIME BY FUZZY LOGIC To get the best washing performance optimal time is determined by sensing the water temperature, selected washing temperature and laundry amount. 2-3. WATER LEVEL CONTROL This model adopts a pressure sensor which can sense the water level in the tub. Water supply is stopped when the water level reaches the preset level, then washing program proceeds. Spinning does not proceed until the water in the tub reduces to a certain level. water temperature washing time rinse time the best washing performance spin rhythm, time laundry amount FUZZY LOGIC selected washing temperature SENSING EFFECT PROCESSING DETERMINATION 2-4. THE DOOR CAN NOT BE OPENED While program is operating. While Door Lock light is on.

ACCESSORIES Inlet hose(1EA) Option : Hot / Cold(2EA) Spanner

8 4.INSTALLATION INSTALLATION The appliance should be installed as follows. Check the conditions of installation area. 1. Check level ground. On raised foundations or upper level homes, the vibrations can be caused by the type of flooring. It may be necessary to move the machine to a different area in the home or have the floor reinforced to properly support the operation of the unit. 2. Check for humidity or any foreign objects under the feet. Clean the floor, there should be no foreign objects under the feet. If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly and will cause vibrations and slipping. Remove any foreign objects, if any from underneath the machine and level unit properly. See below for examples of foreign objects. 1 Open the box and check appliance condition. 2 horizontal Carpet Paper Laminated paper Purchased stopper Base Packing Washer Spanner 1. Remove the cardboard box and styrofoam packing. 2. Lift the washing machine and remove the base packing. 3. Remove the tape securing the power supply cord and drain hose. 4. Remove the inlet hose from the drum. Keep the spanner provided for future use.

9 Use spanner to remove transit bolts. 3 Check the distance between the appliance and the wall. 4 The tap connection and hose connection must be parallel. 5 Transit Bolt More than 2cm If the distance is less than 2cm, the water supply hose will be kinked or folded. Unfasten 1. Unfasten the adapter ring plate and the 4 adapter retaining screws. 2. Push the adapter onto the end of the tap so that the rubber seal forms a watertight connection. Tighten the adapter ring plate and the 4 screws. 3. Push the water supply hose vertically upwards so that the rubber packing in the hose connects fully to the tap and then tighten it by fastening clockwise. • Water supply pressure must be between 100 kPa and 1000 kPa (1.0 ~ 10.0 kgf / cm 2 ) • Do not strip or crossthread when connecting inlet hose to the valve. • If the water supply pressure is more than 1000 kPa, a decompression device should be installed. • Periodically check the condition of the hose and replace the hose if necessary. Type-A : Connecting Screw-type hose to tap with thread • Fasten the hose connector onto water supply tap. ■ Connecting water supply hose Step1 : Check the rubber seal of the inlet hose Step2 : Connect hose to water tap • Two rubber seals are supplied with the water inlet hose. They are used for preventing water leaks. Make sure the connection to taps are sufficiently tight. Upper connector Rubber packing Plate Water supply hose Fixing screw Hose connector Rubber seal Type-B : Connecting Screw-type hose to tap without thread 1. Unfasten the 3 bolts with the spanner supplied. 2. Take out the 3 bolts along with the rubber bungs by slightly twisting the bung. 3. Close the holes with the caps supplied. Keep the transit bolts for future use.

10 Please use the horizontal tap Horizontal tap Extension tap Square tap 1. Unfasten the adapter ring plate and the 4 adapter retaining screws. 2. Remove the guide plate if the tap is too large to fit the adapter. 3. Push the adapter onto the end of the tap so that the rubber seal forms a watertight connection. Tighten the adapter ring plate and the 4 screws. 4. Pull the connector latch plate down, push the inlet hose onto the adapter, and release the connector latch plate. Make sure the adapter locks into place. After completing connection, if water leaks from the hose, repeat the same steps. Use the most conventional type of faucet for water supply. In case the faucet is square or too big, remove the guide plate before inserting the faucet into the adaptor. Ring plate Guide plate Latch plate Type-C : Connecting one touch type hose to tap without thread Step3: Connect hose to washer • Make sure that the hose is not kinked or crushed. When your washer has two valves. • The inlet hose with the red connector is for the hot water tap. • If the washer has two valves, energy is saved by using the hot valve. After connecting inlet hose to water tap, turn on the water tap to flush out foreign substances (dirt, sand or sawdust) in the water lines. Let water drain into a bucket, and check the water temperature.
